The Internet of Things (IoT) is a network consisting of physical objects, devices, vehicles, buildings, and other items that contain embedded technology to communicate and interact with each other. Each object is uniquely identifiable and has the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.
So how does it work?
The Internet of Things consists of three components:
Physical world objects – This includes sensors/devices that can be connected to Wi-Fi or other network connections. These sensors collect data that are used to perform an action in the physical world.
Network connectivity – This is the communication medium that connects the physical device to the IoT platform where data is stored in the cloud and analyzed. The most common mediums are Wi-Fi and cellular networks like 4G; however, Bluetooth, LoRaWAN, RFID, and NFC are all IoT communication protocols as well.
IoT platform – This is the backend system responsible for processing large amounts of data from multiple devices through different protocols. The IoT platform also allows developers to create applications that can use this data for analytics purposes.
The Internet of Things (IoT) is a sprawling set of technologies and use cases that has no clear, single definition.
However, we can define it as the following:
The Internet of Things (IoT) is a universe of connected “things” and people – all of which collect and share data about the way they are used and about the environment around them.
An IoT ecosystem consists of web-enabled smart devices that use embedded processors, sensors and communication hardware to collect, send and act on data they acquire from their environments.
These smart devices connect with each other and other web-enabled devices and systems – so many, in fact, that it’s estimated that by 2020 there will be well over 50 billion connected things operating across the globe.
At the most basic level, IoT is the concept of connecting any device with an on/off switch to the Internet (and/or to each other). This includes everything from cell phones, coffee makers, washing machines, headphones, lamps, wearable devices and almost anything else you can think of. This also applies to components of machines, for example a jet engine of an airplane or the drill of an oil rig. As I mentioned before, if it has an on/off switch then chances are
The Internet of things (IoT) is the network of physical devices, vehicles, home appliances, and other items embedded with electronics, software, sensors, actuators, and connectivity which enables these things to connect and exchange data, creating opportunities for more direct integration of the physical world into computer-based systems, resulting in efficiency improvements, economic benefits, and reduced human exertions.
IoT allows objects to be sensed or controlled remotely across existing network infrastructure. IoT devices collect useful data with the help of various existing technologies and then autonomously flow the data between other devices. The term “Internet of Things” was coined by Kevin Ashton in 1999.
The Internet of Things (IoT) is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers (UIDs) and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.
The definition of the Internet of Things has evolved due to the convergence of multiple technologies, real-time analytics, machine learning, commodity sensors, and embedded systems. Traditional fields of embedded systems, wireless sensor networks, control systems, automation (including home and building automation), and others all contribute to enabling the Internet of Things.
In 2008, the Global Standards Initiative on Internet Governance (GSIoIG) defined the IoT as “the infrastructure of the information society.” The IoT allows objects to be sensed or controlled remotely across existing network infrastructure, creating opportunities for more direct integration between the physical world and computer-based systems, and resulting in improved efficiency, accuracy and economic benefit in addition to reduced human intervention. Each thing is uniquely identifiable through its embedded computing system but is able to interoperate within the existing Internet infrastructure. Experts estimate that the IoT will consist of almost 50 billion objects by 2020.
The Internet of Things (IoT) is a scenario in which objects, animals or people are assigned unique identifiers and given the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.
IoT has evolved from the convergence of wireless technologies, micro-electromechanical systems (MEMS) and the Internet. The concept may also be referred to as “the Internet of Everything” (IOE). The IoT allows objects to be sensed or controlled remotely across existing network infrastructure, creating opportunities for more direct integration of the physical world into computer-based systems, and resulting in improved efficiency, accuracy and economic benefit in addition to reduced human intervention.
The emergence of IoT has created an enormous amount of data that is unstructured, leading to big data analytics challenges. Currently, most IoT systems are not easily scalable due to the lack of interoperability among devices and information sources.
The U.S. Department of Defense’s DARPA program is exploring how IoT can create a better battlefield environment by connecting soldiers with their surroundings. Other major investments include smart cities and transportation systems such as smart cars.
IoT is the abbreviation of “The Internet of Things”. We can also call it IOT. This technology helps us to control our devices, home appliances and other things over the Internet.
There are many electronic devices which we can connect to the Internet. We can also connect our home appliances with the help of IoT. We can then control them through the Internet from any part of the world.
We know that thousands of things or objects are connected with each other through IoT. They continuously exchange data about themselves and their environment with others. They use this data for taking intelligent decisions.
In simple words, we can say that the Internet of Things is a network of physical objects or “things” embedded with electronics, software, sensors and connectivity to enable it to achieve greater value and service by exchanging data with the manufacturer, operator and/or other connected devices. Each thing is uniquely identifiable through its embedded computing system but is able to interoperate within the existing Internet infrastructure. Experts estimate that the IoT will consist of about 30 billion objects by 2020.
Some Key Advantages:
The major advantages of IoT are:
It improves efficiency by simplifying tasks like turning on/off lights, doors etc.
It helps in energy saving as it can automatically
The term “Internet of Things” is everywhere. The Internet of Things – the idea that everyday objects can be connected to the Internet – is an idea that has been around since at least the early 1990s. The concept, in fact, predates the public Internet itself. The first use of the phrase “Internet of Things” has been attributed to Kevin Ashton. Ashton was a researcher at MIT’s Auto-ID Center, which worked on a global standard for RFID tags and readers.
In 1999, Ashton wrote a presentation that he used to describe the project’s goals and vision to potential investors. That presentation has become famous because it is a good explanation of the concept behind the Internet of Things. Here’s an excerpt:
Today computers – and, therefore, the Internet – are almost wholly dependent on human beings for information. Nearly all of what we know about cyberspace comes from what people have seen, heard or published; in short, from documents created by human beings for human beings.
The problem is, people have limited time, attention and accuracy – all of which means they are not very good at capturing data about things in the real world. And that’s a big deal because things matter more than words.
